a. ROI-based T1 & T2 for edema, IMH and remote myocardium from matched T1 and T2 maps. b. Changes in T1 & T2 after subtraction of the reference values of remote myocardium. Edema had higher T2 than both remote myocardium or IMH. T1 can be used to discriminate between edema, IMH and normal myocardium, though the distributions may overlap. Edema and IMH can be classified with higher specificity using both T1 and T2.
